Hi,
I have a .40S&W SW99 AS Since this is a close relative to the P99, I was hoping you guys wouldn't mind if I asked this question here.
I bought it used and for the first 400 rounds, it performed flawlessly. Then I had a stretch of about 4 weeks where I could not go to the range. During that time, I kept the SW99 as my home defense weapon since it was so flawless. Then when I returned to the range a couple weeks ago, I had failure to feed about three times on every magazine. At first I chalked it up to the two new magazines I bought but I hadn't marked them so I didn't know for certain which mags were doing this. So, when I got home, I marked all the mags and today I made a chart of all my mags and carefullly fed three loads through each mag. These are all the Mec-Gar 12 round mags BTW. They all had multiple FTFs. In some cases, it wouldn't even feed the first round. The lower edge of the feedramp would catch the flat face of the bullet and it would get stuck. In other cases, the leading edge of the bullet would somehow drop lower than the rear of the bullet and the face of the bullet would jam against the front of the magazine.
I tried stretching the mag spring to place more pressure on the bullet. That didn't work. I tried adding a paper spacer between the red plastic piece and the spring so that the nose of the bullet would be pushed up more than the rear. That seemed to work at first but then that mag failed as well.
I'm stuck now. I can't rely on this gun at all. Curiously, my most reliable gun is my little .380 PPK. It fires every time, regardless of what I feed it.
Any ideas?
The only thing that is nagging to me is this... Each night before I go to bed, I slip a loaded magazine into the SW99 and set it under my bed. I do not rack the slide and I load that mag with the slide in the forward position. There seems to be a rather short spring near the top that must be overcome in order to fully seat the magazine in the gun. If I load the mag with the slide in the rearward position, that little spring pressure near the top is absent. Have I bent something by jamming the mag in with the slide in the forward position?
Thanks for any help you can offer.
